The AirTAC AirTAC SDA80X70SB Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 70mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA80X70SB is a double-acting, single-rod compact cylinder engineered to deliver substantial force within a minimal axial footprint. By utilizing a short riveted body assembly, it significantly reduces mounting depth compared to conventional round-body units, yielding a theoretical push of 2513.3 N and pull of 2267.8 N at 0.5 MPa. This specific configuration includes a built-in piston magnet for position sensing alongside a male M22x1.5 threaded rod end.
Designed for demanding motion tasks, the hard-anodized 80 mm bore operates between 0.15 and 1.0 MPa while accepting PT3/8 air ports. End-of-travel deceleration is handled strictly by fixed NBR bumpers rather than adjustable pneumatic cushions, meaning operators should moderate approach speeds or utilize external shock absorbers for heavy loads. The integrated magnetic ring interfaces directly with AirTAC reed or electronic switches fitted into the body grooves.

Uses the 2513.3 N extend force to positively eject heavy formed metal panels from progressive die tooling, where the short riveted body minimizes press interference.
Raises lowerator forks handling 128.1 kg payloads with a 2:1 safety margin, relying on the 25 mm rod and male M22x1.5 thread for secure mechanical coupling.
Drives the sealing head assembly on high-speed corrugated box lines, requiring the -S magnet and an electronic switch to trigger adhesive application precisely.
When sizing this 80 mm bore unit, consider stepping down to the SDA63 which provides 1558.6 N of push at 0.5 MPa, or moving up to the SDA100 which yields 3927 N at the same pressure. With a computed safe working load of roughly 1508 N (about 60 percent of the 0.5 MPa output) and a vertical lift capacity near 128.1 kg using a 2:1 safety margin, this model fits heavy-duty positioning. To order, confirm the 80 mm bore, 70 mm stroke, PT3/8 porting, the -S magnet requirement, and the -B male M22x1.5 rod thread.
Keep in mind that a standard double-acting cylinder will not maintain its position if air pressure drops or the directional valve centers; the piston will drift. The fixed NBR bumper only slows travel near the stroke endpoints and does not function as a locking brake. If your application demands fail-safe load holding, incorporate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This 80 mm bore double-acting cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, increasing to 3518.6 N push and 3175 N pull at 0.7 MPa. The theoretical maximum force is 513 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa and a speed of 30-500 mm/s.
No, it uses fixed NBR bumpers at both ends to decelerate the stroke, not adjustable air cushions; external shock absorbers are recommended for high-energy loads. Additionally, the -B option specifies a male M22x1.5 threaded piston rod instead of the default female M14x1.5 thread.
